Title: Polynomial divider for the GF(2) field in which the coefficient of the highest degree term has a value of one and is not stored in a register
Inventor: SYMES DOMINIC HUGO
IPC: G06F7/72
Filed: 2008-03-26
Abstract: Disclosed is an apparatus and method for dividing polynomials in the GF(2) field. The apparatus has an instruction decoder that generates control signals, a register bank of registers and processing circuitry. The instruction decoder when it receives a polynomial divide instruction generates control signals for the processing circuitry to divide a denominator polynomial by a numerator polynomial, both stored as a set of coefficients in the register bank. The polynomial division gives a quotient polynomial and a remainder value. The denominator polynomial is assumed to have a coefficient of one for its highest degree term and this value is not stored within the register bank storing the values of the rest of the denominator's coefficients. The polynomial is of degree N, with the register being an N-bit register and the register bank having a plurality of said registers. The polynomial divide instruction may be part of a scrambler or encryption program.

Title: Spectrally stabilized broadband optical source
Inventor: TAVERNER DOMINO
IPC: G01J3/51
Filed: 2008-09-12
Abstract: Methods and apparatus enable compensation of source light wavelength fluctuations due to instability of a broadband source within an optical sensing system such as a fibre Bragg grating sensor for strain, displacement, flow, corrosion, chemical composition, temperature or pressure, or a gyroscope.

Abstract: 591,075. Code telegraph receivers. AUTOMATIC TELEGRAPH & RADIO TRANSCEIVER CO., Ltd., and SMART, J. H. April 26, 1945, No. 10541. [Class 40 (iii)] In a telegraph recorder of the type in which a pivoted armature oscillates in the pole-gap of a permanent magnet under the influence of signal currents applied to a fixed coil surrounding the armature, the latter is extended longi, tudinally at its free end by a tongue, a point on which is also fixed, and the recording member is operated from a point of approximately maximum oscillation of the armature-tongue assembly. Received signals are fed to a fixed coil b, Fig. 1, and move a magnetic armature 1 and a springy tongue 2 fixed thereto to one side or the other of the pole-gap of a permanent magnet a. This movement is transferred to a ' hollow, ink-carrying stylus 4a, Fig. 4, mounted on a saddle-piece 5, pivoted in a bridge 7, by two pins 8 projecting downward from the said saddle. The armature 1 is pivoted at one end, and the tongue 2 is restrained by adjustable stops 3, Fig. 1, which may be movable along the tongue so that the armature-tongue assembly can be tuned to the frequency of the received signal elements, for example the dot recurrence frequency when the morse code is being received. The amplitude of the recorded markings depends on the length of stylus 4a projecting forward of the saddle 5. The tongue 2 may be perforated for lightness.
